Long wearing composition for making up eyes, skin, and lips

ABSTRACT

A composition for making up the eyes and skin comprised of a liquid carrier containing at least one film forming polymer, and dispersed therein at least one organic pigment forming the main color component of the composition as well as a method for improving the wear of cosmetic compositions for making up eyes and skin comprising formulating said products with one or more organic pigments in an amount sufficient to improve the wear of the cosmetic composition.

TECHNICAL FIELD

The invention is in the field of compositions for application to eyebrows and eyelashes to impart color, or for use in lining the eyes with color, or application to the skin as in a facial or body tattoo, or the lips as a semi-permanent lipcolor.

BACKGROUND OF THE INVENTION

Many women use a variety of products to beautify the eyes, including brow color, eyeshadow, mascara, and eyeliner. Such products accentuate the eyes and in the case of lash products, will also give the appearance of longer lashes.

One of the common problems with eye products such as liners and mascara is that they often do not wear for long periods of time and have a tendency to smudge. With respect to eyeliner, more adventurous consumers have addressed this problem by having “permanent” eyeliner essentially tattooed onto the eyelids. This is a permanent cosmetic procedure and the eyeliner is not removable.

Cosmetic manufacturers are constantly exploring new formulas for such products that will fill the need gaps of longer wear and reduced smudging in a way that will not necessitate visits to beauty salons to have permanent cosmetics tattooed into the skin. The desired cosmetics should provide long lasting, durable wear, preferably one or more days, and be removable by the consumer whenever desired. In addition, the color should be rich and as natural looking as possible.

Typically, products for making up the eyes contain inorganic iron oxide pigments in an emulsion. Iron oxides are water insoluble and are generally ground with one or more oils in the composition to form what is referred to as a pigment grind. For example, traditional mascaras are mixtures of waxes, oils, and inorganic pigments. They may be anhydrous or in the emulsion form. Many of the so-called water resistant mascaras are anhydrous while traditional mascaras are often in the emulsion form. These types of mascaras are generally applied to the lashes and wear for periods of time ranging from several hours to one day. Users usually remove what remains of such products at the end of the day by washing with water. Another problem associated with such mascaras is their tendency to smudge when the user becomes warm or wears eye makeup that is oily. Moreover, since such products contain significant levels of wax and oil, the inorganic pigments that provide color may tend to be muted. This in turn provides a more artificial look to mascara coated lashes.

Similarly, eyeliner is usually a liquid product or in a pencil form. It is applied to the upper and lower lids to accentuate the eye area. While eyeliner is a very desirable beauty product, it tends to smudge very readily, especially when worn on lower lashes. The smudging is due, in part, to the solubilizing of the dried eyeliner formula by skin oils, perspiration, and tears. Again, the iron oxides typically used to provide color to such products are muted and matte in tone, sometimes providing an artificial look to the liner especially when the color is very dark.

The major need gaps in the field of lash, brow, and liner products relates to creating a color that has a rich, deep, natural tone, and at the same time providing a product that has the capability of extended wear (one or more days) if desired by the consumer, and where negative tendencies such as smudging upon exposure to perspiration, tears, and environmental assaults are reduced or eliminated.

Organic pigments are well known for use in cosmetic compositions. They are particularly desirable because the colors provide a very rich intensity that is not found with traditional inorganic pigments. However, because most organic colors are water soluble, it is difficult to incorporate them into long wearing cosmetics because if the cosmetic user comes into contact with the water such as perspiration, raindrops, etc. the organic pigments readily dissolve in the water and tend to run on the skin and hair. Further, organic pigments are generally not compatible in non-aqueous systems at any appreciable concentration, so they cannot be used in amounts large enough to impart significant color to the composition.

The object of the invention is to prepare products for making up the eyes and skin, such as mascara compositions (or lash tints), brow color, eyeliner, facial or body tattoos that exhibit extended wear, look natural, provide a rich color, and exhibit reduced smudging.

Another object of the invention is to provide eye or face products that are capable of wearing for one to five days and provide a natural appearance.

Another object of the invention is to provide commercially acceptable, stable, products for making up the eyes where the color is obtained with the use of organic pigments.

Another object of the invention is to provide a method for improving the wear of eye or face (the term “face” including lips) product using organic pigments in an amount sufficient to improve wear.

SUMMARY OF THE INVENTION

The invention comprises a composition for making up the eyes and skin comprising a liquid carrier containing at least one film forming polymer, and dispersed therein at least one, preferably a mixture, of organic pigments forming the main color component of the composition.

The invention further comprises a method for improving the wear of cosmetic compositions for making up eyes and skin comprising formulating said products with one or more organic pigments in an amount sufficient to improve the wear of the cosmetic composition.

Preferably the composition exists in a single phase, rather than in emulsion (water-in-oil or oil-in-water) form. The term “single phase” means that the composition exists in one homogeneous phase (such as an oil phase) and the organic pigments used in the composition are dispersed in that phase and the film forming polymer is solubilized in that phase. The term “single phase” also means that one or more of the film forming polymers and the organic pigments may be dispersed in the liquid vehicle and both are compatible and stable therein. In the latter situation, while the film forming polymer may not be completely soluble in the liquid vehicle, it is capable of dispersing in sufficiently small particles throughout the liquid vehicle, remaining dispersed therein in a stable manner, and compatible therewith. In either case, when the composition is applied to the desired surface, the liquid carrier evaporates at least in part and the film forming polymer sets on the surface trapping the pigment particles that were dispersed in that phase on the surface. Preferably, the composition of the invention has a viscosity ranging from 1000 to 500,000, more preferably 5000 to 250,000, most preferably 7000 to 120,000 centipoise at 25° C. The organic pigments used in the claimed compositions comprise the main color component of the composition. The term “main color component” means that the organic pigments are present in an amount sufficient to provide color to the composition, meaning that if the amount of organic pigment which is present is removed the color of the composition will be different when a sample of that composition is drawn across the back of the band, for example, and visually observed with the naked eye. Preferably, the organic pigments provide at least about 0.1-95%, preferably at least about 45-80%, most preferably at least about 80-90% of the color of the claimed composition. In the most preferred embodiment, the organic pigments provide about 100% of the color of the claimed composition (meaning that when the entire pigment concentration is measured, the percentage of organic pigments in the entire pigment load is reflected in the percentage mentioned). It is possible that the claimed compositions may contain one or more inorganic pigments including but not limited to metal oxides such as titanium, iron, oxides such as black, red, yellow, green, and blue, and similar organic powders.

The compositions of the invention may be in the liquid, solid, or semi-solid form. Preferably, the compositions are liquids or semi-solids.

I. Pigments and Particulate Fillers

A. Organic Pigments

The composition of the invention preferably comprises about 0.05-30%, preferably about 0.1-25%, more preferably about 0.5-20% by weight of the total composition of one or more organic pigments or salts thereof. The organic pigments should be dispersible in the liquid carrier. Particularly preferred are organic pigments that are red, green, blue, yellow, violet, orange, and mixtures thereof. Also suitable are Lakes of such pigments, which means that the organic pigments are reacted with a metal salt such as calcium, aluminum, barium, zirconium, and the like to form salts. Particularly preferred are aluminum Lakes of the organic pigments, which is where the organic pigment is reacted with aluminum to form the aluminum salt. Formation of the metal salt of the organic pigment will generally convert the pigment from a water soluble pigment into a water insoluble pigment. Examples of organic pigment families that may be used herein include azo, (including monoazo and diazo), fluoran, xanthene, indigoid, triphenylmethane, anthroquinone, pyrene, pyrazole, quinoline, quinoline, or metallic salts thereof. Preferred are D&C colors, FD&C colors, or Lakes of D&C or FD&C colors. The term “D&C” means drug and cosmetic colors that are approved for use in drugs and cosmetics by the FDA. The term “FD&C” means food, drug, and cosmetic colors which are approved for use in foods, drugs, and cosmetics by the FDA. Certified D&C and FD&C colors are listed in 21 CFR 74.101 et seq. and include the FD&C-colors Blue 1, Blue 2, Green 3, Orange B, Citrus Red 2, Red 3, Red 4, Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2; Orange B, Citrus Red 2; and the D&C colors Blue 4, Blue 9, Green 5, Green 6, Green 8, Orange 4, Orange 5, Orange 10, Orange 11, Red 6, Red 7, Red 17, Red 21, Red 22, Red 27, Red 28, Red 30, Red 31, Red 33, Red 34, Red 36, Red 39, Violet 2, Yellow 7, Yellow 8, Yellow 10, Yellow 11, Blue 4, Blue 6, Green 5, Green 6, Green 8, Orange 4, Orange 5, Orange 10, Orange 11, and so on.

The organic pigments form the main color component of the invention meaning that the color of the composition is attributable to the organic pigments. While inorganic oxides may be incorporated into the composition, the main color of the lash tint (which is black or brown) is due to the organic pigment. In the preferred embodiment of the invention the lash tint is a rich dark brown or black in color, which is achieved through the use of a combination of organic pigments which are not black or brown in color. The rich deep brown or black color may be achieved by combining organic pigments or Lakes thereof in the red, green, yellow, blue, violet, and orange family. Preferably the lash tint comprises a mixture of red, green, yellow, and blue organic pigments or Lakes thereof and is deep brown or black in color. In the most preferred composition the pigments comprise a mixture of red, green, yellow, and blue organic pigments wherein the pigments are Lakes, namely they are in the form of water insoluble aluminum salts. These preferred compositions may comprise organic pigments in non-Lake form however, since such pigments are water soluble, when used in large amounts such non-Lake organic pigments may be incompatible with the liquid carrier. If non-Lake organic pigments are present, they are generally present at about 0.0001-3%, preferably about 0.0005-1% by weight of the total composition at most. The most preferred compositions of the invention are dark brown or black in color and are free of iron oxides, particularly black iron oxide, or contain such iron oxides in amounts less than about 5-10% by weight.

The above mentioned powders may be surface treated with lecithin, amino acids, mineral oil, silicone oil or various other agents either alone or in combination, which coat the powder surface and render the particles more lipophilic in nature.

II. Liquid Carrier

The composition comprises about 0.1-85%, preferably about 5-80%, more preferably about 10-75% by weight of the total composition of a liquid carrier for the film forming polymer and the organic pigments, which may comprise one or more oils or other liquid materials. Preferably the liquid carrier is anhydrous. The term “anhydrous” means that water is not intentionally added to the composition. A variety of ingredients may be suitable including volatile oils, nonvolatile oils, and mixtures thereof. In the most preferred embodiment of the invention the inorganic pigments are insoluble in the liquid carrier, e.g. they are dispersed rather than solubilized in the liquid carrier.

A. Volatile Liquids

The term “volatile” means that the oil has a measurable vapor pressure, or a vapor pressure of at least 2 mm. of mercury at 20° C. The term “nonvolatile” means that the oil has a vapor pressure of less than 2 mm. of mercury at 20° C. Preferably, the compositions of the invention contain a significant portion of volatile solvents as the liquid carrier. Suitable volatile oils are liquids, and enable easy formulation of the composition of the invention. When the composition of the invention is applied to the desired surface, the volatile solvent of the invention must be capable of flashing off to leave the other ingredients in the composition affixed to the surface. Suitable volatile solvents generally have a viscosity of 0.5 to 10 centipoise at 25° C.

Linear and cyclic volatile silicones are available from various commercial sources including Dow Corning Corporation and General Electric. The Dow Corning volatile silicones are sold under the tradenames Dow Corning 244, 245, 344, and 200 fluids. These fluids comprise octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, hexamethyldisiloxane, and mixtures thereof.

2. Paraffinic Hydrocarbons

Also suitable as the volatile liquid are various straight or branched chain paraffinic hydrocarbons having 5 to 40 carbon atoms, more preferably 8-20 carbon atoms. Suitable hydrocarbons include pentane, hexane, heptane, decane, dodecane, tetradecane, tridecane, and C₈₋₂₀ isoparaffins as disclosed in U.S. Pat. Nos. 3,439,088 and 3,818,105, both of which are hereby incorporated by reference. Preferred volatile paraffinic hydrocarbons have a molecular weight of 70-225, preferably 160 to 190 and a boiling point range of 30 to 320, preferably 60-260 degrees C., and a viscosity of less than 10 cs. at 25 degrees C. Such paraffinic hydrocarbons are available from EXXON under the ISOPARS trademark, and from the Permethyl Corporation. Suitable C₁₂ isoparaffins are manufactured by Permethyl Corporation under the tradename Permethyl 99A. Another C₁₂ isoparaffin (isododecane) is distributed by Presperse under the tradename Permethyl 99A. Various C₁₆ isoparaffins commercially available, such as isohexadecane (having the tradename Permethyl R), are also suitable.

B. Nonvolatile Liquids

The liquid carrier may also comprise low viscosity non-volatile liquid oils such as silicones, esters, and the like. If the nonvolatile oils are too heavy or greasy it may hamper the long wearing characteristics of the invention. Generally, the viscosity of the nonvolatile oils if present should range from about 11-1000, preferably less than 100 centipoise, most preferably less than about 50 centipoise at 25° C. Examples of such oils include polyalkylsiloxanes, polyarylsiloxanes, and polyethersiloxanes. Examples of such nonvolatile silicones are disclosed in Cosmetics, Science and Technology 27-104 (Balsam and Sagarin ed. 1972); and U.S. Pat. Nos. 4,202,879 and 5,069,897, both of which are hereby incorporated by references.

Particularly preferred is where the liquid vehicle comprises a mixture of volatile silicone and volatile paraffinic hydrocarbons which serve as the carrier in which the organic pigments are dispersed.

III. Film Film Forming Polymer

The composition preferably comprises 0.1-35%, preferably 0.5-30%, more preferably 1-25% by weight of the total composition of one or more film forming polymers. The film forming polymer (or film former) may be soluble or dispersible in the liquid carrier and when the composition is applied to the desired surface, the liquid carrier at least partially evaporates and causes the film forming polymer to form a film on the surface which holds the organic pigment particles in place with the network created by the hardened polymer. The term “soluble” means that the film forming polymer is soluble in the liquid vehicle and when combined both components form a homogeneous single phase. The term “dispersible” means that the film forming polymer is readily dispersed in the liquid vehicle and forms a stable, heterogeneous composition where the dispersed polymer remains stable and suspended in the liquid vehicle and is compatible therewith (without settling out, for example). The film forming polymer also has adhesive properties, meaning that when incorporated into the claimed composition and applied to the lashes, the film forming polymer forms a film or a weld on the lashes. Such a film will have adhesive and cohesive strength, as is understood by those skilled in the art. Further, the preferred film forming polymer will be capable of forming an semi-permanent film on the surface to which it is applied, meaning that the composition containing the polymer is not removed from the surface to which it is applied with simple soap and water immediately after application.

A variety of film forming polymers may be suitable so long as they are soluble or dispersible in, and compatible with, the liquid carrier; are capable of forming a film on the lashes that may be removed with a remover; and are compatible with the pigment and the liquid carrier. Such polymers may be natural or synthetic and are further described below.

A. Synthetic Polymers

1. Copolymers of Silicone and Ethylenically Unsaturated Monomers

One type of film forming polymer that may be used in the compositions of the invention is obtained by reacting silicone moieties with ethylenically unsaturated monomers. The resulting copolymers may be graft or block copolymers. The term “graft copolymer” is familiar to one of ordinary skill in polymer science and is used herein to describe the copolymers which result by adding or “grafting” polymeric side chain moieties (i.e. “grafts”) onto another polymeric moiety referred to as the “backbone”. The backbone may have a higher molecular weight than the grafts. Thus, graft copolymers can be described as polymers having pendant polymeric side chains, and which are formed from the “grafting” or incorporation of polymeric side chains onto or into a polymer backbone. The polymer backbone can be a homopolymer or a copolymer. The graft copolymers are derived from a variety of monomer units.

One type of polymer that may be used as the film forming polymer is a vinyl-silicone graft or block copolymer having the formula:

Also suitable for use are one or more naturally occuring polymeric materials such as resinous plant extracts including such as rosin, shellac, and the like.

IV. Other Ingredients

A. Plasticizers

It is desirable to incorporate one more plasticizers into the composition. Since the preferred compositions tend to have a lower viscosity when compared to standard mascaras, the plasticizer will improve the spreadability and application of the composition to the surface to which it is applied. The preferred compositions contain one or more plasticizers in an amount sufficient to improve spreadability and application of the composition when compared to the same composition without the plasticizer. Suggested ranges of plasticizers range from about 0.01-20%, preferably about 0.05-15%, more preferably about 0.1-10% by weight of the total composition. A variety of plasticizers are suitable including Suitable plasticizers include glyceryl, glycol, and citrate esters as disclosed in U.S. Pat. No. 5,066,484, which is hereby incorporated by reference. Examples of such esters include glyceryl tribenzoate, glyceryl triacetate, acetyl tributyl citrate, dipropylene glycol dibenzoate, and the like. Also suitable, are plasticizers of the following general formula:

wherein R₁, R₂, and R₃ are each independently a C₁₋₂₀ straight or branched chain alkyl or alkylene which may be substituted with one or more hydroxyl groups. Preferably, R₁ is a C₃₋₁₀ straight or branched chain alkyl; R₂ is a C₂₋₈ alkyl which may be substituted with one or more hydroxyl groups; and R₃ is a C₃₋₁₀ straight or branched chain alkyl. Examples of such compounds include dioctyl malate, diisopropyl adipate, dibutyl adipate, dibutyl sebacate, dioactyl azelate, dioctyl succinate, dioctyl fumarate, and the like. Preferred is where R₁ and R₃ are a branched C₈ alkyl, R₂ is a C₂ alkyl substituted with one hydroxy group, which is dioctyl malate.

Preferred plasticizers are the glycerol, glycol and citrate esters, in particular acetyl tributyl citrate.

B. Viscosity Modifiers

It may also be desirable to include one or more viscosity modifiers in the composition. In particular, since the preferred compositions exhibit a viscosity that is slightly reduced, inclusion of the viscosity modifiers, which will, specifically increase viscosity, cause the composition to have more body and less tendency to run or drip when applied to the desired surface. Suggested ranges of such viscosity modifiers are about 0.01-60%, preferably about 0.05-50%, more preferably about 0.1-45% by weight of the total composition. Preferred are where the viscosity modifiers are not waxes or wax like materials. Suitable viscosity modifiers include natural or synthetic montmorillonite minerals such as hectorite, bentonite, and quaternized derivatives thereof which are obtained by reacting the minerals with a quaternary ammonium compound, such as stearalkonium bentonite, hectorites, quaternized hectorites such as Quaternium-18 hectorite, attapulgite, carbonates such as propylene carbonate, bentones, and the like. Particularly preferred is Quaternium-18 hectorite.

Also suitable as the viscosity modifier are various polymeric compounds known in the art as associative thickeners. Suitable associative thickeners generally contain a hydrophilic backbone and hydrophobic side groups. Examples of such thickeners include polyacrylates with hydrophobic side groups, cellulose ethers with hydrophobic side groups, polyurethane thickeners. Examples of hydrophobic side groups are long chain alkyl groups such as dodecyl, hexadecyl, or octadecyl; alkylaryl groups such as octylphenyl or nonyphenyl

Another type of viscosity modifier that may be used in the compositions are silicas, silicates, silica silylate, and derivatives thereof. These silicas and silicates are generally found in the particulate form. Particularly preferred is silica.

In the most preferred embodiment of the invention, the compositions are free of wax viscosity modifiers, meaning synthetic and natural waxes such as synthetic wax, castor wax, ceresin, rice wax, and the like, or contain such viscosity modifiers in substantially reduced amounts, generally less than 10% by weight, preferably less than 5% by weight, most preferably less than 1% by weight.

The invention is also directed to a method for improving the wear of cosmetic compositions for making up eyes and skin comprising formulating said products with one or more organic pigments in an amount sufficient to improve the wear of the cosmetic composition.

The wear of the cosmetic composition is improved by including amounts ranging from 0.1-99%, preferably 0.5-85%, more preferably 10-75% by weight of the cosmetic composition of organic pigments. Most unexpectedly, including organic pigments in such compositions greatly increases their wear, meaning that they stay on the surface to which they are applied and provide color for a longer period of time than compositions which do not contain organic pigments. While organic pigments were previously known for providing color, the fact that they are able to increase the wear of a cosmetic composition was not known. In a further preferred embodiment of the claimed method, the wear of the cosmetic composition can be even further improved if the organic pigments are combined with one or more film forming polymers as defined herein. The phrase “improving the wear” means that the composition containing the organic pigments will stay on the skin or hair or lashes longer, e.g. more than one day, and even from one to three days without being removed by soap and water.
